The GC-CGX is used to connect a Global Caché IR output (GC-100 or iTach) to a Xantech IR input. Global Caché IR outputs are converted to meet the IR input requirements for a Xantech IR distribution environment. IR signals from 30KHz to 72KHz can now be sent through an existing Xantech IR installation directly from one of our units. The GC-CGX is optically isolated to ensure circuit isolation and protection.
